If Bruce Willis Tweets, you should totally make a chubby black cop named "Al" for his opponent.

If he rolls a Yahtzee, you could make it pop up a message that says "Yippee Ki Yay, Roy!"

Because of my near-encyclopedia knowledge of 80s pop culture, I just had a bunch of ideas. Then again, who knows how many 80s celebrities are playing your game.

Ahah, don't try this with Liam Neeson, or he's gonna find his way up to you and kick your ass.

[LordKano]

With Liam Neeson, I'd try a different tack. I'd make the opponent Joey Rosselini.

[cestith]

I'd make it The Beast from Krull.

Bruce Wayne... Bill Cutting... Darth Maul... the possibilities are endless!

[animal531]

What about Jar Jar Binks? But perhaps that would be too evil.

Or, worse, try out some improv.
